Frequently Asked Questions
What is configuration hardening?
Configuration hardening reduces a system's attack surface by disabling unneeded services, tightening permissions and applying secure settings. Standards such as CIS Benchmarks provide detailed guidance for each operating system.
Why use Ansible for hardening?
Ansible is agentless and uses idempotent playbooks, so you can apply the same secure baseline repeatedly across many hosts without causing unwanted changes. It also makes hardening auditable through version control.
How do I turn CIS benchmarks into Ansible playbooks?
Map each benchmark recommendation to a task or role, test it on a staging host and run it in check mode first. The Codelivly Ansible room is free and walks through this process hands-on.
